Framework for the Parallelized Development of Estimation Tasks for Length, Area, Capacity, and Volume in Primary School – A Pilot Study

Abstract: The purpose of this study is to present a framework for the development of parallelized estimation tasks for the visible measures length, area, capacity, and volume. To investigate if there are differences between the estimation types of task, a written estimation test for 3rd- and 4th-graders was developed. It includes eight different types of task for each measure. The percentage deviation of the estimated value from the real value (the measured size) of 137 students indicates that there are differences between the four measures as well as within the types of task that affect over- and underestimation and the estimation accuracy. Further research could address relations between the estimation of visible measures and the investigation of more characteristics in an estimation task, using a written estimation test that is based on this valid framework.
